TIRE FOR VEHICLE-WH EELS.

SPECIFICATION forming part of Letters Patent No. 682,633, datedSeptember 17, 1901.

Application iled''ebruary 20, 1901. Serial No. 48,096. (No model.)

To @ZZ whom it may concern:

Beit known that I, WILLIAM F. MASTERS, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Tires for Vehicle-Wheels, of which the following is a full and complete specification,such as will 4enable those skilled in the art to which it app'ertains tomake and use the same.

This invention relates to tires for vehicles; and the object thereof isto provide an improved tire which is particularly adapted for use inconnection with heavy vehicles, such as express-wagons, trucks, andother vehicles designed for heavy loads, but which may also be used inconnection with lighter vehicles, if desired.

The invention is an improvement on that described and claimed in UnitedStates Letters Patent granted tome November 20, 1900, No. 622,008, andis fully disclosed in the following specication, of which theaccompanying drawings form a part, in which the separate parts of myimprovement are designated by the same reference characters in each ofthe views, and in whicha Figure l is a side view of a portion -of thewheel of avehicle provided with my improved tire; Fig. 2, a transversesection thereof; Fig. 3, a view similar to Fig. 2, showing amodification 5 and Fig. 4, a-modilication of a detail of theconstruction.

In the drawings forming a part of this specification I have shown at 5 apart of the rim of the wheel of a vehicle, which in practice is composedof separate fellies, which make up said rim and with which in practicethe spokes 6 are connected, and said rim is provided at its oppositesides with an annular groove 5a, and around the rim 5 is placed a steelband 7, which is bolted to the rim 5, as shown at 8, and this steel band7 serves to securely bind the rim and spokes together in the manner ot'an ordinary tire.

Around the steel band 7 is placed a rubber band 9, and around the rubberband 9 is placed a band 10 of wood, which is preferably thicker than thesteel and rubber bands 7 and 9, and around the band 10 of wood is placeda thick steelband 1l, which constitutes a tire proper.

. The outer steel band ll is made comparatively thick and is provided atits inner perimeter and at its opposite sides with an annular groovella, similar to the grooves 5 in the rim 5, and the steel band ll, theband 10 of Wood, the rubber band 9, and the inner steel band 7 make up acomposite tire, the separate members of which are bound together byannular metal plates 12, which are preferably composed of separatesections, as shown in Fig. l, and said metal plates are held in place bybolts 13, which are passed therethrough and through the Wooden band 10.

It will be observed that the wooden band 10, the rubber band 9, and thesteel band 7 are of less width in transverse section than the body ofthe rim 5, and the body of the outer steel band 11 and the metal plates9 lit in the annular grooves 5 and 11a, formed in the rim 5 and in theouter steel band 1l.

In the normal position of the composite tire there is an annular spacebetween the inner edges of the plates 12 and the body portion ot` therim 5, which permits the movement of the tire when the vehicle isheavily loaded, said movement being occasioned by the compression of therubber band 9, and by means of this construction I provide a tire whichpossesses great elasticity and at the same time great durability and bymeans ot' which the vehicle is prevented from jolting and jarring whenheavily loaded, which is also an injury thereto, and the Wheelsthemselves are made very durable, as are also the separate parts of thevehicle.

In Fig. 3 I have shown'a modification in which a supplementalrubber band14 is placed between the main outer steel band 11 and the band 10 ofwood, and this construction is employed where greater'elasticity isdesired. It will be observed that the metal side plates 12 aresubstantially iiush with the sides of the rim 5, and the outer steelband 1l, which constitutes the tire proper, is preferably slightly Widerand extends beyond the metal plates l2, the object of this constructionbeing to give the tire a wider tread and also to give the wheel greaterstability and strength.

The thickness of the separate bands of steel, rubber, wood, and4 steelmay be regulated as desired, this thickness depending toan ex- IOO tentupon the character of the vehicle to which the tire is applied.

In the case of extremely heavy vehicles instead of making the band lOWithin the outer steel tire entirely of Wood I may also make it of metaland Wood, as shown in Fig. 4, in which I employa ring or band IO,composed of metal and Wood, the metal constituting an outer casing 10b,having side flanges or rims Within which is placed a band 10C, of Wood,and in practice the metal side plates are secured in place by boltspassed through the wooden ring or band and the side iianges of the metalcasing.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A Wheel provided with the usual rim,. the sides of which are providedat the perimeter thereof with annular grooves, and a tire consisting ofan inner band of steel, a band of rubber, a band of Wood, and an outerband of steel provided at its inner edges with annular grooves and metalside plates bolted i to said band of Wood and inclosing the inner bandof steel, the band of rubber, and the band of Wood, substantially asShown and described.

2. A Wheel, the rim of which is provided at its perimeter with annularside grooves, and a tire consisting of an inner band of steel, a band ofrubber, a band of Wood, another band of rubber, and an outer band ofsteel, the last-named band being provided with annular side grooves atits inner perimeter and side plates bolted to the band of Wood andinclosing the inner band of steel and the bands of rubber and Wood,substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing Witnesses, this 18th day ofFebruary, 1901.
